It's not a good movie but I give it 6 for its charm and some of the gender differences shown. How for Supergirl the first concern is not to get raped. And how beautiful the flying was when she was not imitating superman.
Didn't enjoy it that much as i thought i will be. I remember it from my youth years with fond but it was pretty lame. Nothing happened in the movie, everything was so fast and without any plot. Bad for a b-movie as well.
